Bayesian coarsening: rapid tuning of polymer model parameters

Refinement and coarsening of Bayesian networks

In almost all situation assessment problems, it is useful to dynamically contract and ex­ pand the states under consideration as assess­ ment proceeds. Contraction is most often used to combine similar events or low probability events together in order to reduce computa­ tion. Expansion is most often used to make distinctions of interest which have significant probability in order to improve 't...

Adaptive Tuning of Model Predictive Control Parameters based on Analytical Results

In dealing with model predictive controllers (MPC), controller tuning is a key design step. Various tuning methods are proposed in the literature which can be categorized as heuristic, numerical and analytical methods. Among the available tuning methods, analytical approaches are more interesting and useful. This paper is based on a proposed analytical MPC tuning approach for plants can be appr...

Estimation of genetic parameters of litter size in Moghani sheep using threshold model via Bayesian approach

This study was conducted to estimate the genetic parameters of litter size (LS) in Moghani sheep using threshold model via Bayesian approach. The data originated from the Jafar-Abad Station of Ardabil province, Iran, and included 9698 lactation records of 4977 ewes with lambings from 1995 until 2010. The pedigree file consisted of data on animals born from 1987 to 2010. The significance of fixe...

Development of a Molecular Kinetic Model and Tuning of its Required Kinetic Parameters for Thermal Cracking of Light Hydrocarbons

Polymer elasticity-driven wrinkling and coarsening in high temperature buckling of metal-capped polymer thin films.

We report the critical effects the deformational stress from the elastic nature of a confined polymer layer has during the relaxation process on the buckling of thin metal-polymer bilayer systems (less than 100 nm) even above the temperature at which the polymer is in the liquid flow region. In contrast with what is generally believed, the dispersion force does not play a significant role in th...
